IDT723611
IDT723611 is CMOS SyncFIFO manufactured by Integrated Device Technology.
FEATURES
:
- Free-running CLKA and CLKB may be asynchronous or coincident (permits simultaneous reading and writing of data on a single clock edge)
- 64 x 36 storage capacity
- Synchronous data buffering from Port A to Port B
- Mailbox bypass register in each direction
- Programmable Almost-Full (AF) and Almost-Empty (AE) flags
- Microprocessor Interface Control Logic
- Full Flag (FF) and Almost-Full (AF) flags synchronized by CLKA
- Empty Flag (EF) and Almost-Empty (AE) flags synchronized by CLKB
- Passive parity checking on each Port
- Parity Generation can be selected for each Port
- Supports clock frequencies up to 67MHz
- Fast access times of 10ns
- Available in 132-pin Plastic Quad Flatpack (PQF) or space-saving 120-pin Thin Quad Flatpack (PF)
- Low-power advanced CMOS technology
- Industrial temperature range (-40o C to +85o C) is available, tested to military elecrical specifications
DESCRIPTION
:
The IDT723611 is a monolithic, high-speed, low-power, CMOS Synchronous (clocked) FIFO memory which supports clock frequencies up to 67MHz and has read access times as fast as 10ns. The 64 x 36 dual-port FIFO buffers data from Port A to Port B. The FIFO has flags to indicate empty and full conditions, and two programmable flags, Almost-Full (AF) and Almost-Empty (AE), to indicate when a selected number of words is stored in memory. munication between each port can take place through two 36-bit mailbox registers.
